Hm. Having examined the state of affairs, I must ask; who in this war has been spending HUGE numbers of earth gems in blighting me? Having examined Tien Chi's unit roster, I find it unlikely that it is they who have turnd my provinces into a wasteland.
The T'ien Ch'i don't like how you've implied it may have somehow been an inefficient use of gems. Therefore I suggest you suspect the Tir na n'Og, only they could be so reckless. Mmhm.
